Specification of Letters Patent.

Patented March 3,1908.

Application filed July 17, 1907. Serial No. 884,174.

T 0 all whom it may concern:

Be it known that we, ALEXANDER Zinc and FREDERICK V AN ZEGK, citizens ofthe United States, and residents of Grafton, in the county of Taylor andState of West Virginia, have invented a new and Im roved HeatingApparatus, of which the fol owing is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved heatingapparatus, ar

ranged to heat the water in a hot water radiator by the use of steam, tokeep the hot water radiator supplied with water by the water ofcondensation of the steam, and to maintain a uniform-level of waterin'the hot water radiator, thus combining steam and water heating in avery effective manner and permitting the use of the apparatus in allclasses of buildings, including high buildings in which the excessivepressure from a regular hot Water system would prevent its use.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

- Figure 1 is a sectional side elevation of the improvement; Fig. 2 isan enlarged cross section of the main fitting, the section being on theline 2-2 of Fig. 4 Fig. 3 is an end view of the same viewed in anopposite direction from Fig. 2, and Fig. 4 is a sectional side elevationof the same on the line 44 of Fig. 2.

The hot water radiator A consists of a first or front section A,intermediate sections A and a rear or last section A connected with eachother in the usual manner, and to the lower portion of the front sectionA of the radiator A is secured a main fitting B, connected with thesteam supply pi e C, having a valve D and leading to a. boi or or othersuitable source of steam supply. To themain fitting B is secured one endof a steam pipe E, extending lengthwise through the ower portion of thehot water radiator A, to connect at its rear end by a pipe F, with therear end of a perforated steam distributing pipe G, extending lengthwisein the upper portion of the radiator A.

Above the upper inner end of the front section A is a block or plug Aand the upper end of the said front section A is connected by anoverflow pipe H with the main fitting B, the said overflow ipe H beingprovided with asuitable chec valve I, to prevent the steam from passingby way the pipe H into the upper end of the first section'A of theradiator A. The block or plug A serves to obstruct the communicationbetween the first and second sections and to form a seal between theoverflow pi e H and the distributing pipe G. Now by t e. arrangementdescribed, steam can ass from the boiler or other su ply by way 0 theipe C and valve D into the main fitting B, rom which the steampassesthrough the pi e E to'heat the water contained in the radiator Aand to insure a rapid circulation of the water in the several sectionsof the radiator. The steam after assing through the pipe E passes upthroug the pi e F into the condensing pipe G,- in whic denses and passesby way of the perforations in the said pipe into the radiator A, tosupply the latter with water. All surplus water is carried ofl throughthe overflow pi e.-H, so that the level of the water in the ra iator Ais maintained at a uniform height, the overflow water returning to theboiler the same as in an ordinary steam heatin apparatus.

From the foregoing it will be seen that the water in the hot Waterradiator is heated by the use of the steam passing through the pipe E,and by causing the water of condensation of the said steam to ass intothe radiator, the latter is supplie with water and the level of thewater in the radiator is maintained at a uniform height by the overflowpipe H. By the arrangement described no sudden change of temperature ofthe Water in the radiator takes place, as the same water level in theradiator is. maintained and the temperature of the water is raisedevenly but very rapidly. The tern erature is controlled by the o eratormanipu ating the valve D in the usua manner.

The overflow pi e H enters the radiator a distance from t .e topthereof, so as to maintain an emptyspac'e in the upper portion of theradiator for the pipe G to extend in, and to allow space for expansionof the water without dan er of producing an undesirable pressure wit iinthe radiator.

The main fitting B is rovided with a chamber'B, opening into t einterior of the front radiator section A, and this chamber B is adaptedto be connected by a suitable valve J, with the chamber into which opensand connecting the said pipes.
